When one of the tabs in a JTabbedPane is in fact a Container containing
Components, then those Components on the Container are visible, even though the
tab is not selected. They remain visible until you select and then deselected
the tab containing the Components (tab2 in example).

For more details:

Reproduce it this way:
1) Launch the program
2) You (incorrectly) see the label belonging to tab2 although tab1 is selected
3) Switch to tab3
4) You (incorrectly) still see that label belonging to tab 2
5) Switch to tab2, and then switch to tab1 (or tab 3)
6) Now tab2 is correctly hidden. Once tab2 has ever been selected, tab2 and all
of its sub-components are correctly hidden and revealed.

Using this application:

import java.awt.*;
import javax.swing.*;

public class TabBug extends Frame
{
    public static void main(String[] params)
    {
Frame f = new Frame();
f.setSize(300,300);
f.setLayout(new BorderLayout());

JTabbedPane tabs = new JTabbedPane();

tabs.add(new Label("Tab 1"),"Tab 1");
Container c = new Container();
c.setLayout(new FlowLayout());
c.add(new Label("Tab2 (label in container)"));
tabs.add(c,"Tab 2"); // at this moment, c.setVibible(false) is fired. That doesn't have the desired effect.
tabs.add(new Label("Tab 3"),"Tab 3");

f.add(tabs);

f.show();
    }
}
